This is an expression if she only gets pedicure
y = 35

If she wants to get massage, multiply the cost for a minute with the number of minutes.
Find cost per minute first
cost = 50/20
cost = 2.5

y = 35 + 2.5x
y = 2.5x + 35

Which recursive formula can be used to generate the sequence shown, where f(1) = 5 and n &gt; 1?
AlladinOne [14]
The sequence of numbers decrease by 6 each time, so we can write:
f(1) = 5
f(2) = -1
f(3) = -7
f(1) - f(2) = 6
or:
f(2) = f(1) - 6
which means:
f(n + 1) = f(n) - 6

What is the answer for x
alexandr402 [8]

Answer:

x = 8.5

Step-by-step explanation:

I got this answer by assuming the triangles were congurent, if they are not, the answer may vary.  

first, make an equation:

x + 8 = 3x - 9

bring 3x to the other side, by subtracting it

-2x + 8 = -9

Subtract 8

-2x = -17

divide by -2

x = 8.5

Then, just sub x into the formulas
